摘　　要：应用X衍射全谱分析方法，对中药材牛黄等8个样品进行了衍射分析研究，获得了牛黄、人工牛黄、管黄、人胆结石、猪胆结石不同拓扑特征的衍射图和特征标记峰。在不同的实验条件下计算得到特征标记峰d值的误差分布曲线，并由此成功地识别了由厂家提供的牛黄与人工牛黄3个样品。表明X衍射全谱分析方法可用于传统中药材鉴定，为中药形态与显微组织鉴定提供了佐证。Investigation on famouse Chinese herbal medicine-Niu huang(calculus bovis) was car-ried out by all-spectrum X-ray diffraction analysis. Dlffraction spectrums, as well as the spe-cif ic symboling peaks of calculus bovis, artificial bezoar, bile ductstone, human gallstoneand hog gallstone, were recognized. The error distribution curves of d^bd for specific sym-boling peaks was also obtained by ca1culation under diffrent testing conditions, by which weidentified successfully three samples provided by a pharmaceutical factory. This articleshows that all-spectrum X-ray diffraction analysis can be used to identify Chinese traditionalcrude drug, and provides for morphologica1 and microscopical study.
